【摘要】 本文提出了一种利用Unitary ES PRIT(UES PRIT)算法提取任意源的信号参数的方法,再结合反向射线追踪技术以及城市电子地图便能对目标源进行三维定位。文章首先推导分析了如何提取任意目标源的信号参数提取,然后简要概述了反向射线追踪技术。本文以高斯脉冲源为例做了一系列数值论证,数值结果证明本文提出的方法可以同时高效的估计视距源和非视距源。更多还原

【Abstract】 In this paper, an parameters estimation method for arbitrary signal source based on the unitary ESPRIT algorithm is proposed. Arbitrary 3-D source can be located by that method together with the back ray tracing technique and the city electronic maps. At beginning of this paper, the formulas and algorithm for extracting signal parameters from the arbitrary source is deduced and analyzed. Then, a brief sketch of the back ray tracing technique is made. At the end, we take Gaussian pulse for example. Numerical results demonstrate that this position method can locate both the line of sight (LOS) and non-line of sight (NLOS) sources efficiently.更多还原
